Does Anyone know how to convert hysys case from new version to old version, say from hysys aspen v 7 to hysys v 3.2
because I only have hysys 3.2 running in my PC
In the newer version, save the file as .XML file (Go to Save As, and from the drop-down menu choose XML). These files can be opened by earlier versions of Hysys.
Just be careful. I have done exactly that and I had to go through the file on the older version of Hysys to ensure that the correct flows passed through. This is really important if your simulation has recycle loops or distillation columns.
